This paper provides a general overview of arc spraying and its various uses in industry. It discusses the basics of the technique, the types of wires and powders used, and typical applications for a wide range of arc-sprayed metals and composites. It also discusses special cases and considerations such as wear protection in corrosive atmospheres, high-temperature corrosion protection, surface rebuilding and reprofiling, coating thickness, and the effect of different elements. Paper includes a German-language abstract.

This paper reviews the principles of cathodic corrosion protection and the different ways zinc anodes are applied to reinforced concrete through wire arc spraying. It also explains how the lifetime of zinc coatings can be extended with an organic topcoat and presents related test data. Paper includes a German-language abstract.

This paper describes an arc spraying process developed for the production of metalized film capacitors. It discusses the role of metal spraying in capacitor manufacturing, the basics of thermal spraying, and the function of various components in a wire arc spraying system. It also reviews the production steps typically used for capacitor end spray. Paper includes a German-language abstract.

Structural damage in concrete structures caused by corrosion is widespread and demand comprehensive repair work. The additional installation of an active corrosion protective systems for structures being located in unfavourable conditions is imperative. Thermally sprayed coatings serving as anode have been adapted from the cathodic protection of steel. These systems have gained attention as they offer advantages in efficiency and lower cost. Thermally sprayed zinc coatings are applied to new steel reinforced concrete structures or those which are subject to re-structuring. In this contribution, the capability of various systems is examined by field tests in a marine structure and in different laboratory tests under natural and under accelerated conditions.

Structural damage caused by corrosion in concrete structures is widespread and requires extensive repair work. The installation of corrosion protection systems for constructions that are under unfavorable conditions is urgently necessary. Thermally sprayed coatings serving as anode have been developed from the cathodic protection of steel. These systems have attracted attention because of their performance and lower cost advantages, and they are about to enter the competitive anode system market. Thermally sprayed zinc coatings are applied to the surfaces of steel-reinforced concrete components that are affected by corrosion. In this article, the ability of the system to deliver a protective current is verified by field tests in a marine structure in the Arabian Gulf that was discussed in 1997. Paper includes a German-language abstract.
